Here’s how the Raiders graded out in Sunday’s 37-6 loss to the Denver Broncos.

Pass offense

Carson Palmer (19 of 34, 202 yards) did some good things early but couldn’t convert in the red zone and found himself increasingly under pressure as the Broncos expanded their lead. Palmer threw his best deep ball of the season — a 37-yard sideline strike to Denarius Moore — and a couple nice screens. Grade: C+

Rush offense

Darren McFadden gained 15 yards on his first three carries, a promising start that went nowhere. He finished with 34 yards on 13 carries. The longest gain went to Mike Goodson on a 13-yard run. The Raiders needed to run to keep Denver’s pass rush at bay and failed. Grade: F

Pass defense

Target practice, fish in a barrel, pitch-and-catch, use any descriptive clichés you want and that’s what Peyton Manning did to the Raiders defense. He completed 30 of 38 passes to eight receivers for 338 yards, three touchdowns and no interceptions, had zero pressure. It all looked so easy. Grade: F

Run defense

Denver’s no-huddle offense set a tempo the Raiders simply couldn’t match, and it showed up in the Broncos running game, which got better as the game went on. Willis McGahee gained 112 yards on 19 carries, and Ronnie Hillman, who had just 8 yards on three touches coming in, had 31 yards on 10 attempts. Grade: D-

Special teams

A deflected punt by David Bruton, who got far enough inside Brandon Myers and made a perfectly timed leap, led to a short-field Denver touchdown drive. Taiwan Jones had two nice stops on punt returns of Jim Leonhard but later got a face mask penalty. Punt returns? That would mean the Broncos actually punted. They didn’t. Grade: C-

Coaching

The Raiders had all the reason in the world to come out in the second half ready to play. They trailed just 10-6 when it could have been 20-3, but they unraveled. Three-and-outs followed by Denver touchdowns. Sorry, but can’t agree with Dennis Allen’s “compete until the end” stance with Palmer. He needed the hook for his health. Grade: F
